Title: Improvements in or relating to polarographic apparatus
Inventor: GLASTONBURY HAROLD AUSTIN
IPC: G01N27/48
Filed: 1952-08-14
Abstract: 745,904. Polarographic apparatus. MAY & BAKER, Ltd. Aug. 11, 1953 [Aug. 14, 1952], No. 20509/52. Class 37. Polarographic apparatus using a dropping mercury electrode is characterized in that the drop is made to fall cyclically at a predetermined instant in the voltage sweep either (a) by a cyclic cessation of the sweep voltage producing an equivalent reduction in the surface tension, or (b) by the addition of a periodic voltage pulse to the sweep voltage to make it exceed that corresponding to the maximum surface tension. As shown, Fig. 1, the sawtooth sweep voltage applied across a polarographic cell A is developed across a condenser C 1 by charging from a battery B1, the mercury drop being made to fall by discharging condenser C1 by operating a switch K1. Alternatively, at the desired point in the voltage sweep a positive pulse is applied to the anode of the cell A by operation of a-second switch K2. The starting value of the sweep voltage is adjusted relative to the drop-life by a back E.M.F. from a potentiometer P1, and the voltages across the cell A and a series resistor R1 are taken, after amplification, to the X and Y plates of a C.R.O. Switches K1, K2 are operated together by a cyclically energized relay in the anode circuit of one of a pair of valves connected as a multivibrator.

Title: Device for detecting and rejecting imperfect containers
IPC: G01M3/34
Filed: 1955-07-16
Abstract: 837,881. Testing containers. FILLING MACHINES Ltd., and WILSON, A. July 18, 1956 [July 16, 1955], No. 20663/55. Class 106 (2). [Also in Group XXX] A device for detecting and rejecting containers which are imperfect to a degree sufficient to prevent the formation of air-tight seals when lids are applied, incorporates feeding means adapted to feed containers to a testing-point, means adapted to hold each container stationary for a short period of time at the testing-point, means at the testing-point for creating a partial vacuum in each container being tested, the degree of partial vacuum attained being dependent on the presence or absence of imperfections which would cause leakage of air into the container, and means sensitive to the degree of partial vacuum formed to accept or to reject the container. As shown, glass jars 28 are carried on a conveyer belt 1 which moves each jar in turn into a position in which it is arrested by an escapement member 2. The latter is reciprocated transversely by cam gear 7, 8 in timed relation with the passage of articles to stop each article at the testing-point and then release it. A pusher 3 is urged by a spring 4 in a direction to push a container at the testing point into a siding 1A but is prevented from doing this by a detent 22 associated with a lever 20 which is pivoted at 21 and provided with a counterweight 23, the detent being normally wedged in a groove in the pusher but being released each time the escapement member is moved into position to entrain a container, in which position a pin 3A on the pusher is engaged in a slot in the escapement member 2. In this position the counterweight temporarily releases the detent 22, but at this moment a testing head 24 consisting of a lid member equipped with sealing means is lowered by cam mechanism 9, 10 on to the container, and a piston 15 is simultaneously moved upwardly in a cylinder 13 by crank gear 17 to create a partial vacuum in both the container 28 and a cylinder 18. If the rim of the container makes a perfect seal with the testing head, a piston 19 connected to the lever 20 is moved downwardly in the cylinder 18 to move the detent into operative position so that the pusher is maintained in retracted position. If, however, the rim of the container does not make a perfect seal with the testing head the degree of vacuum is insufficient to move the detent into operative position so that on subsequent movement of the escapement member 2 to release the container the pusher moves with the member 2 to direct the container into the siding 1A. The bottles may be fed to the testing-point by a star-wheel instead of an endless belt, the drive to the star-wheel being arranged to be disconnected when the escapement member is entraining a container. Specification 698, 873 is referred to.
